I have used the stock clutch and the K-Factory clutch bells, all with the stock shoes at present... 13 and 14T bells...
Both seem fine so far, but after 2 gallons my clutch bearings are pretty much shot, so I am waiting on some newuns (and surplus stock)
Hey Mark
get in touch with "Roach" on Maxbashing as he is pretty much THE person to see about bearings in the UK

plus i know hes just got in 200 clutch sized bearings last week
